The Explore Scientific AR152, with its larger aperture (6") gathers 44% more light over the AR127 (5") model, providing much brighter images and higher resolution. Our goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field large aperture refractor. Images of deep sky objects are stunning at low powers. At high power the moon and the planets are revealed in sharp, high contrast.
Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series telescopes come with heavy-duty, high quality components, including a 2" dual-speed Crayford-style focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 finderscope and quick release bracket, and a cradle ring assembly with Vixen-style dovetail mount. Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you'll be ready to discover the Universe!
AR152 Air-Spaced Doublet Refractor Highlights
152mm f/6.5 optical design. The tube assembly is constructed from aluminum and stainless steel and painted gloss white. Classic Crown & Flint Air-Spaced Doublet achromat optics. Research-grade, diffraction limited surfaces. Enhanced Multi-Layer Coatings (EMD) are deposited on all optical elements to boost contrast and eliminate light scatter. While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending off to the factory is an option, but is not required. Come with a heavy-duty 2" two-speed focuser. The light-weight 2" diagonal has 99% dielectric coatings for high contrast, bright images. A 1.25" compression ring adapter is included. Includes an 8x50 straight-through finderscope with a wide 6° field of view, with front objective focus. To attach your Explore Scientific Air-Spaced Doublet telescope to a variety of mounts, we have included an extra strong extruded aluminum Cradle Ring Assembly and Universal Adjustable Mounting Plate. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others. All Explore Scientific products come with a STAR Transferable Extended-Life-of-the-Product Warranty. Upon registration, this product will be under warranty for as long as it is manufactured, plus five years.
